In the confidence interval method the sample data must come from a population that is normally distributed with no outliers.
A confidence interval is a range of values derived from observable data at a desired level of confidence that may include the parameter's true value. The confidence level, such as a 95% confidence level, refers to the accuracy of the estimating process rather than the degree of assurance that the computed confidence interval accurately represents the true value of the parameter under investigation. Confidence intervals are typically written as (some value) ± (a range). The range can be expressed as a percentage or as a real amount. The equation used to determine the confidence interval varies depending on which standard deviation is known.

Answer:
A natural monopoly can occur when the average cost of making a good decreases a lot as output increases
Explanation:
A natural monopoly can occur when the average cost of making a good decreases a lot as output increases. An example of this is the electricity. It requires cables, towers, transformers and other electrical equipments, etc. So, in this case is not viable to have multiple providers.
Introverts often have a small group of close friends. To those who know them, they’re often great listeners, can give thoughtful advice, and are extremely empathetic. A person who is severely shy may find it difficult to form close friendships like that, and can remain feeling awkward even around family and people they have known for their entire lives. An introvert can be fine with someone approaching them and beginning a conversation, but to someone who’s shy, that can be just as terrifying as the thought of starting a conversation themselves.
A big difference between the two is how the person feels about their lack of social interaction or desire for constant companionship. An introvert is fine with it: They really, really are. To an introvert, it’s not a problem to be alone with their thoughts or to have a quiet dinner with one or two close friends. For someone who’s shy, though, they tend to wish that it just wasn’t the case. They are the ones that long for a big group of friends, but just can’t bring themselves to reach out and put themselves into that situation.
